Summaryinfo

A vulnerability marked as critical has been reported in Texas Instruments OMAP L138. Affected by this issue is the function SK_LOAD of the component TEE. Performing a manipulation results in stack-based overflow. This vulnerability is known as CVE-2022-25334. Attacking locally is a requirement. No exploit is available.

Detailsinfo

A vulnerability was found in Texas Instruments OMAP L138 (the affected version is unknown). It has been classified as critical. This affects the function SK_LOAD of the component TEE. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Texas Instruments OMAP L138 (secure variants) trusted execution environment (TEE) lacks a bounds check on the signature size field in the SK_LOAD module loading routine, present in mask ROM. A module with a sufficiently large signature field causes a stack overflow, affecting secure kernel data pages. This can be leveraged to obtain arbitrary code execution in secure supervisor context by overwriting a SHA256 function pointer in the secure kernel data area when loading a forged, unsigned SK_LOAD module encrypted with the CEK (obtainable through CVE-2022-25332). This constitutes a full break of the TEE security architecture.

The weakness was published 10/19/2023. This vulnerability is uniquely identified as CVE-2022-25334 since 02/18/2022. Technical details are known, but no exploit is available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
